It is an object of the present invention to avoid the above-mentioned
problems and provide a multicolor OLED display with improved power
efficiency that reduces the need for precisely patterning one or more of
the OLED layers. This object is achieved by an OLED display having at
least red, green, and blue colored pixels, including a magenta light
emitting layer provided over a substrate for red and blue pixels and a
green light emitting layer provided over the substrate for producing at
least a green pixel. It is also achieved by first and second color
filters in operative relationship with the magenta light-emitting layer
to respectively produce red and blue pixels.
